IMPROVED MACHINE FOR PULVERIZING AND LEVIGATING SUBSTANCES.

Specification forming part of Letters Patent No. 44,444, dated September 27, 1864; antedatedv September 16, 1864.

To all whom it may concern: I,

Be it known that I, o. E. NOBLE, of Penn Yan, inthe county of Yates and State of New i York, have invented a new and useful Improvement in Attenuating-lvlachines5 and I do hereby declare that the following is a full, clear, and exact description ot' the cont struction and operation of the same, reference being had to the annexed drawings, making t a part ot this speciiication, in whichl Figure l is a side elevation of the wholei machine. Fig. 2 is a longitudinal section of the receptacle. Fig. 3 is a longitudinal secl tion ofthe mortar and pestle. Fig. 4 is a frontview of the cylindrical triturator.

The letters of reference refer to the same I parts in each figure.

A represents the frame that holds the vai rious parts of the machine. lt may he made in any convenient manner so as to hold the journals of the wheels B and G and hold the supports P I?.

B is the driving-wheel of spur-gear. It l drives a pinion on the journal ot' the wheel O and the pinion L. (Represented in Fig. 4.)

U is a blank wheel having the properties of a balance-wheel. It is provided with a crankpin putin the face of it at a proper distance from the center to give the required motion to the slotted rod D. lt is overhung, as represented in Fig. 1.

D is a slotted rod, the slot in the middle. At the upper end a cross-piece that holds 2 the receptacle E. lt is supported by rthe g boxes I and l?, and by them held close to the face ofthe wheel O. It is given a reciprocating motion by means ot' lthe pin F, and when 1 this portion of the machine is not needed the i pin F may be taken out to stop the motion ot' l the receptacle E.'

E is the receptacle that receives and holds the mortar, vial, or whatever contains the medicine that requires attenuating. It is made cylindrical in form at one end, and semicylindrical at the other, as shown in Figs. l l and 2. At the round end is a spring with a pad or cushion attached, against which the t mortar is placed. The use of the spring is to i allow the mortar or vial to be put in its place without moving the sliding-head G; also tot give nnelastic support to the mortar. l

F is the crank-pin in the face of the wheel C that drives the slotted rod D.

.Gr is the sliding head of the receptacle E. It is made in shape as shown in Fig. 2. Itis cushioned inside to make an easy and safe berth for the mortar, for the purpose of preventing breaking mortars when they are made of glass or porcelain. It is provided with a screw that passes down through the receptacle, the screw having a nut upon it. By

means of the screw and nut the head may be moved to suit the length of the mortar.

H is a cylindrical-shaped mortar. It is represented in Fig. 3. It may be made ot' any vmaterial desired, with a joint at or near the middle. Medicine is put into it with the pes- 1 tle I. The mortar is then closed and placed within the receptacle for operation.

I is the sliding pestle. It may be made ot' any desirable material, and made round and solid, with each end made oval, to suit the shape ofthe inside of the mortar H.

J is a frame that supports the other triturating part of the machine. It is shown in Fig. 4. It is made adjustable by means ot' slots in the bottom, through which screws arepassed when this portion of the machine is not used. It may be put out otA gear by moving the frame back far enough to release the pinion L from the wheel B. l

K is the triturating-cylinder. It may be made ot metal, glass, or porcelain. It is securely fastened to the journal that passes through the pinion L and frame J.

L is a pinion attached to the journal of the cylinder K.

M is the hollow cylinder, made in two parts, divided horizontally, with holes at the end for the cylinder-journal to pass through. It may be made of any desirable material or size required. It is used to perfect the trituration after leaving the mortar H.

N is an elastic band that holds the parts of the cylinder M together. A. metallic clasp may be used, if desired.

O is the crank. By it the whole or any part of the machine may be put in motion, as required.

P and P are slide-boxes for the ends of the slotted rod D to pss through, and support the same. They are made secure to the frame Ain any convenient manner, and should be 2. The receptacle E, mortar H, pcstle I, made ofsome good anti-friction material. cylinder K, and eonezwe M, when made as What I claim as my invention7 and desire i specified7 and used for the purpose set forth. to secure by Letters Patent, is- Y O. E. NOBLE.
